Hey there!
The statement 'The distance of a star from the earth is 8.33 light minutes' means that the light from the star takes 8.33 minutes to reach earth.
Given,
Speed of light = 3 * 10^8 m/s
Distance covered in 1 sec = 3 * 10^8
Time taken = 8.33 min = 8.33 * 60 s
Distance = speed * time = 3 * 10^8 * 8.33 * 60 = 1.5 * 10^11 m
Hope It Helps You!
